I just installed LM 6.0 64-bit and I rebooted and now get this error message: Error 15: File not found . As a workaround, I can press ESC while booting to get to a boot select menu, and there select the appropriate hard drive and it boots fine, after some hesitation. Note that: I have 2 TB sata HDs and one 300 MB sata (sda1) system HD in this box. Gosh I hope this is fixable! Any ideas?

Hope this helps, let me know if you need more help, especially if this doesn't work

Nope, didn't work. But after Error 15: File not found Press any key, I see a screen with bright blue letters (and dim gray ones) with duplicate entries.

A little background: I bought some fancy Corsair ram from TigerDirect that apparently required a high performance or "gaming board." I also used a high end 10k Velociraptor 300 HD in the system (nForce 750i SLI 123-YW-W175).

I'm going to replace the sata cables this week to see if that's the problem. Maybe one or two of them is a Sata 150-only when it should be a sata 300 cable.

Ok, I suspect it's having trouble finding a specific kernel version. There's a little trick you can use in mint to always load the most recent kernel, add this to the bottom of your /boot/grub/menu.lst file (needs sudo):

for the root options, copy the info from an existing entry in the "AUTOMAGIC KERNELS LIST". As a quick check, the number in kernel line should (almost certainly) be 1 more than the final number in the root line. Also the letter should correspond to the first number with a=0, b=1 etc.

Reboot, and select the new "Mint Latest" option in the boot menu.
